Answer: 74.6
we draw a right triangle ABC, have: ∠ABC = 90°, AB = 20 and ∠BAC = 75°, the height of the building is BC
we also have: tan 75° = BC/AB = BC/20
=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6
Step-by-step explanation:
Answer:
√22
Step-by-step explanation:
First, let's find the number of lunches:
14*3 = 42
To find how many lunches have ham sandwiches, we multiply the total number of sandwiches by the percentage of the ham sandwiches:
0.55 * 42
Multiply:
23.1
We can round down:
There are about 23 lunches with ham sandwiches
Answer: Substitute in the values of a1=27 a 1 = 27 and r=13 r = 1 3 .
Step-by-step explanation:
As we move from point Z to point Y, x increases by 8 and y increases by 3. Thus the length of line segment ZY is sqrt(8^2 + 3^2) = sqrt(73), by the Pythagorean Theorem. That's approx. 8.54.
You could also leave your answer in the form √(8^2 + 3^2).
